Implement Subtotal or Grand Total Labels in Other Languages with C++

Possible Usage Scenarios

Sometimes, you want to show subtotal and grand total labels in non-English languages like Chinese, Japanese, Arabic, Hindi, etc. Aspose.Cells allows you to do this using the GlobalizationSettings class and Workbook.GetGlobalizationSettings() property. Please see this article on how to make use of the GlobalizationSettings class:

• Using GlobalizationSettings Class for Custom Subtotal Labels and Other Label of Pie Chart

Implement Subtotal or Grand Total Labels in Other Languages

The following sample code loads the sample Excel file and implements subtotal and grand total names in the Chinese language. Please check the output Excel file generated by this code for your reference. We first create a class of GlobalizationSettings and then use it in our code.

#include "Aspose.Cells.h"
using namespace Aspose::Cells;

class GlobalizationSettingsImp : public GlobalizationSettings
{
public:
    U16String GetTotalName(ConsolidationFunction functionType) override
    {
        return u"Chinese Total - \u53EF\u80FD\u7684\u7528\u6CD5";
    }

    U16String GetGrandTotalName(ConsolidationFunction functionType) override
    {
        return u"Chinese Grand Total - \u53EF\u80FD\u7684\u7528\u6CD5";
    }
};

Now use the above-created class in the code like below:

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;

class GlobalizationSettingsImp : public GlobalizationSettings {
public:
    virtual U16String GetTotalName(ConsolidationFunction functionType) override {
        return u"Custom Total";
    }

    virtual U16String GetGrandTotalName(ConsolidationFunction functionType) override {
        return u"Custom Grand Total";
    }
};

int main() {
    Aspose::Cells::Startup();

    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    Workbook wb(srcDir + u"sample.xlsx");

    GlobalizationSettingsImp gsi;
    wb.GetSettings().SetGlobalizationSettings(&gsi);

    Worksheet ws = wb.GetWorksheets().Get(0);

    CellArea ca = CellArea::CreateCellArea(u"A1", u"B10");
    ws.GetCells().Subtotal(ca, 0, ConsolidationFunction::Sum, {2, 3, 4});

    ws.GetCells().SetColumnWidth(0, 40);

    wb.Save(outDir + u"output_out.xlsx");

    std::cout << "Subtotal applied successfully!" << std::endl;

    Aspose::Cells::Cleanup();
    return 0;
}
